2 periods 1 month

I am super super super SCARED! This month I’ve had two periods . I have no exact reason as to why (I’ve never had this happen before) but I have a few theories

1.) I skipped like 4 days of my birth control and then took them all at once and continued the pack normally then stop taking them again

2.) I’ve been having unprotected sex with my boyfriend and he has been nutting on me. Maybe this is implantation bleeding . But I literally just had unprotected sex like maybe last Friday !

3.) breakthrough period from stress and anxiety

What do you ladies think? Also I just got a wax before my period came back and now my little lady is all irritated and I think it’s from the wax being so fresh and I have to wear both pads and tampons . Maybe the blood is irritating me ! Any suggestions ?
